Buying Bac Water Online in the US: What to Check First

By the BacWater.fit team · Updated

Short answer. Buy from a seller that states the concentration (0.9% benzyl alcohol), the vial size and how many vials come in a kit, publishes its prices and shipping, says how long dispatch takes, and sends the lot COA with the order. Skip listings with no lot number, no expiry and no way to ask a question.

The checklist

  • Concentration stated: 0.9% (v/v) benzyl alcohol for bac water.
  • Vial size and kit count stated — no guessing what 'a pack' means.
  • Prices and shipping published before you share any details.
  • A dispatch time you can hold the seller to.
  • The lot COA with the order, and on request before it.
  • A real way to ask: e-mail or chat, with stated hours.

Marketplace listings

General marketplaces often show a product photo and a price and little else. Before buying there, ask for the lot number, the expiry and the COA; if nobody can answer, look elsewhere.

You send an order request and pay once we have confirmed the total — nothing is charged on the site.
